yr 12 Physics. Shows why the power company steps up the voltage to thousands of volts, when transmitting power to the consumer.
a step up in voltage to transmit a current through the power wires, then upon reaching destination, a unit steps down the voltage again.
The transmission lines are made from a high resistance wire, and this simulates the long distance that the electricity has to pass through to reach the consumer/user end point.
The voltage is stepped up in order to decrease the
current, & if there is minimul resistance., and therefore less power loss at other end .. I THINK!!!!
please correct me if I am wrong, I am happy to learn....and dont quote me a s gospel!
It is a model showing the journey of the power between the power station and the consumer.
It even has minature little pylons that have the wire threaded into... for real effect!
I bought mine from Serrata a number of yrs ago.
Looks like a plank of 4x2.
We use the Jackaranda HSC book 2. The unit is
Generators and Power Distribution
